Sudden Sever Acne😩

Help! I've always had very mild acne due to a poor cleansing routine (not washing before bed, not regularly removing makeup) with few breakouts. Half way through my first semester at college i started getting worse acne. I thought it was probably from wearing more makeup regularly and also from the oily and fatty dining hall food, and as a vegan i'm used to eating home cooked meals with whole foods and very little oil. I was getting breakouts in places that i never before had acne! Normally i get it on my chin and forehead but now i have some on my cheeks and jawline, and it's worse than normal around my mouth.

My first week home from school my acne appeared to be slowly getting better and i thought it was from not eating the school food (i stopped going to the dining halls the last 2 weeks and lived solely off groceries) but then it started getting even worse again! I've gotten new skin products and started washing my face 1-2 times daily and wearing makeup less, and it will get better in some spots then worse in others.

Idk what's causing it or what else to try. I know sometimes skin gets worse before it gets better depending on the products you use but idk if that's what it is. Any advice? And could it also be cause by my birth control pills?
